Abstract (en)

A magnetic disk apparatus is capable of reading normal data following a read error of a reference signal that has occurred due to a scratch or the like on a disk surface. In the magnetic disk apparatus, if a reference signal (STM) fails to be read at point P, then an elapsed time (Tw) is measured, and a time T2 indicating the difference between a time T1 at which a read gate is supposed to be opened and the time Tw is determined. The read gate is opened after the time T2 has passed, thereby making it possible to properly read data and subject the read data to a decoding process. <IMAGE>
